Question
Lysosomes are reservoirs of
Options
A.RNA and protein
B.fats
C.secretory glycoproteins
D.hydrolytic enzymes
Solution
Lysosomes were discovered by Christian de DuVe (1955) from rat liver. Matile (1964) discovered lysosomes in plants. Generally lysosomes are 0.2 - 0.8 in in size, irregular mem branous vesicles filled with hydrolytic rnzymes. They are polymorphic. About 40 enzymes (all hydrolytic) are present in lysosomes. These include proteases, nucleases, glycosidases, lipases, phospholipases, phosphatases and sulphatases.
